PLUMB-BOB.

SPECIFICATION forming part of Letters Patent NO. 632,286, datedSeptember 5, 1899.

Application filed March 27, 1899.

To all whom, it may concern.:

Be it known that I, ALBERT A. SNE'BOLD, a citizen of the United Statesof America, residing at Natrona,in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inPlumb- Bobs; and I do hereby declare the following to be a full, clear,and exact description thereof, reference being had to the accompanyingdrawings, which form a part of this specification.-

My inventionl relates to an improved plumbbob; and it consists in adevice whereby the cord used for suspending the said plumb-bob may bereeled and kept within the same, together with certain details ofconstruction In the accompanying drawings, Figure 1 is a side elevationof my improved plumb-bob. Fig. 2 is a similar view, partly shown insection the better to show the internal parts, consisting of the reelfor winding the cord suspending the plumb-bob. Fig. 3 is a plan view ofthe same. Fig. 4 is a plan view of my improved plumb-bob having theupper portion removedA therefrom.

To put my invention into practice with an ordinary plumb-bob constructedand formed in amanner well known in the art` and consisting of a steeltapering or conical point 1 and a corresponding body'portion, this bodyis divided into an upper section 5 and lower section 2, the one joinedto the other by means of a screw-thead 3, formed upon anupwardly-projecting annular collar or sleeve 4, integral with the bodyportion 2, the construction and form of which leaves a circular space 6,in which a reel 7 is placed, the journals 7 of which are journaled inthe aforesaid sleeve 4. Intermediate of the said upper section 5 andlower section 2 of the plumb-bob is a collar S, having a serratedperiphery, by means of which the said collar may be easily revolved bythe operator.

Serial No. 710,606. (No model.)

Forminga part of the above-described collar and arranged about its upperperiphery is a ratchet or gear 9, which engages with a small gear orbevel pinion l0, mounted upon one end of the shaft carrying the reel 7.Attached to this reel 7 is a cord 11, the other extremity of whichprojects through a tensioncap at the top of the plumb-bob, and the saidcord l1 and an attached ring' 12 used ina manner well known in thepractical use of the plumb-bob. This tension device consists of athreaded cap 13, bearing upon a divided gland 14 in a manner that whenthe said cap 13 is screwed downward the gland will bind itself about thecord 11 and prevent the same from moving, or if the said gland isreleased the cord will have a free passage through the ports.

ln operation the cord 11 may be withdrawn to its full extent, but may bestopped at any point by screwing downthe cap 13 (therebytightening theglands 14) and stopping the cord at any point desired. The cord may berewound about the reel 7 by simply turning the serrated collar 8 in theproper direction, which movement will operate the pinion 10 and reel 7to wind or reel the cord 1l.

Having thus described my invention, I claim.

A plumb-bob consisting of the upper and lower section, the one separatedfrom the other by a serrated collar 8, a reel 7 arranged intermediate ofthe two sections operated by the said collar and a locking device,substantially as described for coniining the plumbcord at any desiredposition as described.

In testimony whereof I havev hereunto aflixed my signature in th'epresence of two subscribing witnesses.

ALBERT A. SNEBOLD.
